Using Signaling Services to Send and Receive Messages

Members of an XCF group can send messages to each other and receive messages from each other using a set of macros:

IXCMSGOX for sending messages
IXCMSGIX for receiving messages
IXCMSGC for saving, discarding, reprocessing, forcing a message to completion, or obtaining information about messages.

Note: The IXCMSGOX and IXCMSGIX macro interfaces are the successors to IXCMSGO and IXCMSGI macro interfaces. IBM® suggests using IXCMSGOX and IXCMSGIX to send and receive messages between XCF group members, but in most cases you can continue to use IXCMSGO and IXCMSGI. An XCF group member application program needs to be changed to use IXCMSGOX or IXCMSGIX when functions provided by these macro interfaces are wanted.
